GNAT GPL provides a complete Ada 2012 development environment, including a comprehensive tool-chain as well as AdaCore’s flagship GNAT Programming Studio (GPS) Integrated Development Environment (IDE).  GNAT GPL implements the Ada 2012 language standard by default, which includes these important language features:

  • Contract-based programming (preconditions, post-conditions, and type invariants) including support for the Liskov Substitution Principle in Object-Oriented Programming
  • More general expressions (conditional expressions, quantified expressions, expression functions)
  • Enhanced multiprocessor support (multiprocessor affinity and barriers)
  • Enhanced integration of concurrency and OOP
  • Additional language-defined libraries (vector/matrix libraries)

“With more than 5 million units sold to date, Raspberry Pi is one of the world’s most popular single-board computers for young computer innovators and hobbyists,” said Jamie Ayre, Marketing Director of AdaCore.  “By providing Raspberry Pi 2 users access to the very robust, high-integrity development environment of Ada, we’re opening the door to some really creative solutions and the next generation of Ada programmers.”

With the release of GNAT GPL for Bare Board ARM in 2014, an implementation on the Raspberry Pi 2 running Linux on ARM was a natural follow-up. It reflects AdaCore’s ongoing commitment to the Ada community to provide freely available Ada implementations for developers of nonproprietary software. Fully featured releases of this GNAT technology are also available for GNU Linux, Mac OS X, Bare Board ARM, and Windows.

About Raspberry Pi 2
The Raspberry Pi 2 Model B is the second generation Raspberry Pi, released in February 2015. The 900MHz quad-core ARM Cortex-A7 CPU increases the performance almost 6 times, and the 1GB LPDDR2 SDRAM accommodates larger and faster systems. The Raspberry Pi 2 Model B retains the various interfaces of its predecessor, such as 4 USB ports, 40 GPIO pins, a full HDMI port, and an Ethernet port. With its low cost / high performance advantages, the Raspberry Pi 2 is an attractive choice in many kinds of systems including Internet of Things (IoT) applications.

    GPL editions of GNATbench, AJIS, and PolyORB will be released at a later date.

    SPARK GPL 2015

    SPARK GPL 2015 - the formal method verification toolset - includes a number of major enhancements. New language features include in particular support for Object-Oriented programming and "ghost code" used for proof only, with no impact on the generated code.

    Proof capability has been significantly improved with the integration of two provers by default (Alt-Ergo and CVC4), additional automatic generation of contracts, more precise analysis of modular (bitwise) operations, and improved support for manual provers.

    Usability has also been enhanced through better categorization of messages and output of assumptions made for each verification result.

    SPARK GPL 2015 also ships with additional examples, in particular a standalone TCP/IP stack implementation.

Hi-Lite project officially launched

Yesterday saw the official launch of the Hi-Lite project. Financially supported by French national and local government agencies, Hi-Lite aims to increase the use of formal methods in developing high integrity software, particularly to meet the forthcoming DO-178C avionics standard.

Hi-Lite is completely based on libre software. The project is structured in two different toolchains for Ada and C based on GNAT/GCC compilers, the SPARK verification toolset and the Frama-C platform. The integration of these toolchains inside two industrial IDEs offers to the user a common interaction on Ada and C programs. In particular, mixed Ada/C programs can be verified against a common specification.

The project partners are AdaCore, Altran, Astrium Space Transportation, CEA-LIST, the ProVal team of INRIA and Thales Communications. AdaCore is the project leader. For more information please visit www.open-do.org/projects/hi-lite and to subscribe to the public mailing list please send email to hi-lite-discuss@lists.forge.open-do.org.

This conference brings together experts from the two fields and asks the question “Can Formality and Agility be combined?” to develop software that has to reach the highest levels of safety and security.

The Open-DO Qualifying Machine

A Qualifying Machine (QM) is an agile and lean infrastructure to ease DO-178 tool qualification. The main goal of a QM is to ease the manipulation of all artifacts within the whole application life cycle and to track the activities performed by the development team.

Within Open-DO, we released an instantiation of the QM concept for GNATcheck, a coding standard checking tool qualifiable for DO-178. The infrastructure and qualification material (including the Tool Qualification Plan and the testing framework) are freely available as open source in the Open-DO forge. With this initiative, we intend to promote open collaborations in the high-assurance domain and to show how to deploy a lean and agile qualification process.

Altran and AdaCore Launch SPARK GPL

The launch of a new, General Public License (GPL) version of SPARK brings a professional-grade toolset for high-assurance and safety-critical software development to the academic community and developers of Free Software. This aims to drive the use of high assurance programming techniques and tools by a larger percentage of the overall software development community.
